Can't enable hybrid OVF

Took my X-PRO2 off the For Sale list and went through the menus, setting up things. However, somehow I have disabled the Hybrid OVF mode! Flicking the front lever towards the lens, when in OVF mode, no longer activates the little hybrid LCD insert!

Can't find any way that I could have turned off this mode, or how to reset. Any recommendations? (Might try a factory rest...)
